Objective:To analyze the prenatal three-dimensional ultrasound(3D US)features of skeletal dysplasia and to determine whether 3D US can reveal additional diagnostic information.Methods:Fifteen pregnant women suspected of having fetal skeletal dysplasia with routine prenatal two-dimensional ultrasound(2D US)scan were examined with 3D US.Volume-rendering image with surface and trans-maximum mode was used to reconstruct 3D images.And multi-plane analysis of scanned volume data was also used for diagnosis.The accuracy of 2D and 3D diagnosis for the malformation with detail was compare to pathology outcome.Results:Fifteen cases of skeletal dysplasias included absent skull (n=2),scoliosis(n=1),spinal segmentation defects(n=1),short limbs(n=4),absent up-limbs(n=2),abnormal forearms(n=2),abnormal hands(n=2)and club foot (n=1).All cases obtained 3D US scanned data and 3D image with surface or trans-maximum mode.Prenatal 2D US determined the site of anomaly in 10 cases (66.7%)and described the abnormality in detail in eight cases (53.3%),and for 3D US,they were 15 cases (100%)and 13 cases(86.7%),respectively.Conclusions:The surface characteristics of fetal skeletal dysplasias can be described by volume rendering image with surface mode,and the number and shape of the bony structure can be showed by volume rendering image with trans-maximum mode.3D US provides an important tool for diagnosing fetal skeletal dysplasia,thus 3D US can be used as an important method complementing 2D US.

A three-dimensional pharmacophore of epidermal growth factor receptor tyrosine kinase inhibitors was obtained based upon 3D-QSAR of a series of these inhibitors. The result was accordant with the pharmacophore model given by the scientists at Novartis. The pharmacophore included a hydrogen bond receptor, a hydrogen bond donor, a hydrophobic area and a phenyl ring with a chlorine or a bromine atom. This pharmacophore is very useful for clarifying the structure-activity relationships of EGFR tyrosine kinase inhibitors....
